9362063 Nicholson A new laser crystal, praeseodymium yttrium lithium fluoride, is being proposed for development for applications in holographic interferometry. Most pulsed laser holographic interferometry is presently performed with either frequency doubled neodymium yag or with ruby lasers. There are a number of limitations imposed by either of these tow crystals, some of which will be overcome by the new proposed crystal. Holographic also anticipates the crystal will have significant applications in medicine and elsewhere. Holographics proposes to prove certain aspects of the praseodymium crystal in Phase I, such as making a seed laser and gaining single longitudinal mode in an injection seeded gaussian mirrored oscillator. Improvements in pumping efficiency will be attempted by using fluorescent converter and doped glass converters. ***

小行星9362063 一种新的激光晶体，氟化钇锂，被提议用于全息干涉计量学的发展。 目前，大多数脉冲激光全息干涉测量都是使用倍频钕YAG或红宝石激光器进行的。 这些丝束晶体中的任何一种都有许多限制，其中一些将被新提出的晶体克服。 全息还预计晶体将在医学和其他方面有重要的应用。 全息术提出在第一阶段中证明普鲁士晶体的某些方面，例如制作种子激光器和在注入种子高斯镜像振荡器中获得单纵模。 将尝试通过使用荧光转换器和掺杂玻璃转换器来提高泵浦效率。 ***
